Keyestudio EASY plug ADXL345 Acceleration Module

Introduction

The ADXL345 module is a low power, 3-axis MEMS accelerometer with high resolution (13-bit) and measurement at up to ±16g (gravitational force).
Digital output data is formatted as 16-bit twos complement, and is accessible through either a SPI or I2C digital interface.
The ADXL345 is well suited to measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock.
This module needs to be used together with EASY plug control board.

Special Note:
The sensor/module is equipped with the RJ11 6P6C interface, compatible with our keyestudio EASY plug Control Board with RJ11 6P6C interface.
If you have the control board of other brands, it is also equipped with the RJ11 6P6C interface but has different internal line sequence, can’t be used compatibly with our sensor/module.

Upload the Code

Below is an example code. Open or drag below code to Mixly Blocks and upload the code to your board to check the 3-axis acceleration data and the module's tilt information.

What You Should See

Open the Serial monitor to see the 3-axis acceleration data. See changes as you sway the Accelerometer.

Little Knowledge:
If you think the monitor’s result is too fast to see the data clearly, you can drag a Delay block to add into the source code. Shown below.
After that, upload the code again and open the monitor, you should be able to see the display data clearly.
